PAPER-Box MACHINE` -AND *.rHnLIKE;

Appuomn mea nay is, 1927, serial No.`1e1,6es, and in Germany may 12,192e.

This invention refers broadly to improvements in the manufactureof aperor cardboardboxes and the like and) in particular to that part of theartlin which the cover or lid of the box is mounted automatically and anrapid succession upon the body or ybase part of the box, and it isintended to generally improve the processvof manufacture and the ingbelts or aprons movable in parallel re-v lation to each other andvalternatingly or staggeringly arranged, means being provided inconnection with the device accordin to the invention to cause .the mostadvance lid or base section. to be placed by slides or the likeinsuperposed relation and to be then assembled to each other, whereuponthe'thus connected box sections may be `fed, if desired,-into a deviceor part of machinery by vmeans of which they may for instance be 3oprovided with a wrapper ofv paper or the like.

The supporting yand guiding means for the box sections at. the point uofclosure or assemblage are arranged in such amanner that the box sectionsbefore the mounting of the cover or lid'bmay be automatically trued orsmoothened with accuracy, means being provided to adjust and tocompensate any inaccuracies of the edges ofthe box sections so that ineveryIcase the' lid or cover` may be mounted upon the base section ,ofthe box 1n the regular run of the machine and wlthout any interferingdisturbance.l

.l The invention will be more particularly described by reference-to theaccompanying drawings'showing by vway of example some f forms ofpreferred embodiment of the principles of the invention mFi .1 invertical 1ongitudinal section, and in ig. 2 in vertical transversesection, an'd in'Fig. 3 in planlview. so Figures 4-6 illustrate the modeof operation of the'device forl the assembling of the box sections; andFi 7 is aperspective of the entire box. In Figures-840 a modification isshown which 'is particularly adapted for the smoothening and truing ofthe walls of the box, Fig. 8 showing the parts in front elevation andFig. 9 in plan view, and Fig. 10 the mode of operation of this part ofthe device as applied to the truing of' the walls.

machine by means of the aprons or conveyor belts 1, 2 which are'alternatingly arranged,

and upon which the base sections 3 and the covers Nor lids 4 arerespectively mounted closely adjacent to each other. The m untlin(lr ofthe box sections may be eiected m lnualy or by machinery` in which casethe as# sembling device may be directly united to the box makingmachine. disposed at di'erent levels' and in such a .manner that thebase sections 3 of the boxes are moved at the level ofthe machinevtableAagainst a stop 5 while the covers 4 are fed onto a plate 6 in aguideframe 7. The apron The aprons 1, 2 are or belt 2 and the plate 6are spacedly disposed above the machine table 24 which corresponds,

to a. multiple of the heights of the boxes. A-

to the belts or aprons moves those boX sections 3, 4 which have been thefurthest advanced towards the point of assemblage, causing the basesection 3 of{the .box to come in contactV with a movable stop 10 whichis controlled by a cam disc or the ike, while the cover is moved'against the stationary stops 11. In the forward movement of the coverskor lids 4 they slide from the plate 6 onto the stationary supportingbars 12 and then upon slide 8, 9 which is reciprocate'd transverselytthe spring actuated (yielding) stops 13. n

Underneath the base part `3 which rests against the stops 10' a hollowbar or tube 14 is vertically reciprocated in the frame 15 and its headplate 16 carries the levers 17 pivotally`-secured 4thereto and springactingly forced against the 'plate 18. This plate 18 is movablyconnected to the rod 1.9 which is movable in the tubular bar 14. Theparts 14, 19 are controlled in-any. suitable manner, thus `for instanceby means of cam discs and by the levers 20, 21 cooperating therewith'.On the levers 17 thin plate spring lingers 22 are connected which uponlthe .raisingmofthe tubular bar 14are adapted to pass through slots 23ofthe machine table 24. Above the cover or lid 4 resting against thestop '11 a plun erA or piston 25 is reciprocatingly guided whic is movedin a manner not shown in the they are made to rest against the stops 10,11.

rlhen the spring acting ngers 22 are raised .and are moved past andabout the base sec-A tion 3, and are then allowed to move inwards whichmovement is produced by iirst raising the plate 18 together with thetubular bar 14: and then moving the plate 18 with relation to the leversl? in the highest position the ends of the spring fingers 22 have passedthrough the apertures of the table and have entered into, the covers orlids 4: (Fig. 4). Now, the cover is lowered, while the spring fingers 22and the plunger v25 are descending together and retain the cover betweenthem which slides along the springY actingly yielding supporting bars'3.3. As soon as the cover ap roaches the base section of the box the ens of .the spring ngers 22 are moved outwards causing the cover to betrued and smoothened and to be adjusted with relation to the basesection. 'Ilhis will cause the edges of the cover. in some cases' to bebent somewhat outwards, while the edges of the body of the box areforced somewhat inwards so that 'the cover will be engaged with thebodyl or base part oi the box free Jfrom obstructions (Figo) .whereuponthe spring fingers 22 are lreturned to their initial position (Fig. 6).

i This terminates one cycle of operations; the

slides 3, Qeed the next succeeding box sections into the machine, whilethe assembled finishen box is discharged from the machine past thereviously withdrawn stop 10 and by means o a chute or .conveyor or thelike 27 and may be introduced into a labelling machine or wrappingmachine or the like.

The guiding members for the box sections and other parts of the machinemay be made adjustable, in order to be able to operate on pieces of.work of different sizes. With a corresponding arrangement of the s ringfingers`22 the invention is also ap lica le to oval sha edland roundboxes in e manner l describe the operation being accompanied byanautomatictraning and adjustment of 1 ceuracies ofthe box sections. Onaccount of the accurac of operation of the -machine -it ma be wor` ed atvery highspeed.

n ir

igures 8-13 special means are shown vfor the truing of the edges and thewalls of the box sections, and by means thereof the walls oredges ofthebox sections before or after assembling them into a finished bOx aretreated with the pressing means adapted to force the resilient materialinwards to such I an extent that any of the edges or walls which :modenaby slight inaccuracies or deiciencies of. loperation have become bulgedoutwards are relieved from the irregularities of tension and by theirelasticity after the release of the pressing means will assume theregular vertical and straight position with'relation to each otherinstead of the unsightly bulged out appearance which interferes Agreatlywith the normal and regular assembling of the difterent box sections.

Pressing dies, plungers or the like- 28 and respectively 29 may beemployed for the purpose mentionedl which are arranged at the point ofassemblage of the box sections and which, lafter the box sections havebeen fed to the point of assemblage will exert an in wardly directedpressure against the edges of the box sections at all four sidesthereof. The dies or plungers 28, 29 are rounded off or provided withtorous thickened portions at the point of pressure and are moved forinstance by the `rods 30, 31 or in another suitable manner. They mayhowever also be stationarily or: spring actingly arranged. Either oneofthe pressing members may be preferably mounted on the feeding slide 32for the box sections, while thepressing' members` opposite'therefrom mayserve .as stops for' the advanced box sections. After the pressurebasbeen produced the box sections are assembled in the manner hereinbeforedescribed. j

. ln Fig. 11 of the drawing a modification is shownin which the readilyassembled boxes 3, 4 after their discharge from the assembling deviceare movedthrough channels or pas.- sages 33,34 disposed at right angletoveach other and the side walls of which .are pro- Yvided withresilient or spring acting pressure rollers 35, 36. These rollers forcethe narrow sides of the boxes during their-travel vo' i in the firstplace against the longer side of the boxes, and then the transversesides are all forced inwards, as clearly appears from Figures 11-13 ofthe drawing. 1
